BausH FORWBRONZING AND FOR OTHER PURPOSES.

SPECIFICATION forming part of Letters Patent No. 274,978, dated April 3,1883. Application filed February 14, 1883. (No model.)

To all whom it may concern Be it known that I,JosEPH F. SARGENT, ofWorcester,in the county of Worcesterand State of Massachusetts, haveinvented certain new and useful Improvementsin Brushes for Bronzing andfor other Purposes; and I declare the following to be adescription of mysaid invention sufficiently full, clear, and exact to enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification,

The object of my present invention is, first, to provide a practical andefficient brush or rubberforspreadin g or cleaning off bronze-powderinthe operation of bronze-printing, and for other purposes; second, toafford a simple and convenient bronzing-brush having facilities forsupplying bronze to the surface as'desired. These object I attain bymechanism such as hereinafter described, the particular features claimedbeingdefinitely specified.

In the drawings, Figure 1 represents a plan view, Fig. 2 a part side,part sectional, view, and Fig. 3 a bottom view, of a bronzing-brushconstructed to illustrate the nature of my invention. Figs. 4, 5, and 6are views showing details of construction.

One feature of my invention consists in making the brush from cloth,felt, or textile fabric formed into small rolls and set intoa supportingframe or backing,'ot' wood or other suitable material, so that theendsof said rolls project and present the edge fibers of the fabric in aseries of close tufts, which are properly trimmed ed and leveled to givea soft smooth working-face for distributing and clearing off the loosebronze-powder.

In the drawings, Aindicates the workingface of the brush, which iscomposed of small pieces of fabric A, preferably ordinary cotton clothcut to proper shape and size and formed into small rolls a, which arefolded at their centers and drawn into holes in the frame or brush-backB, and secured by wires or cords b,

l in a manner similar to the fastening of bristlebrushes. Theprojectingends are then trimmed off to givean even uniform surface. Thetufts or rolls of cloth can be set more or less closely to give thedesired density of surface. The back B is bored with a series of holesfor the reception of the rolls in substantially the same manner as forthe construction of a bristlebrush.

The shape of the brush may be made to con form with the requirements ofservice. Oylindrical brushes for bronzing-machines can be made of clothformedinto rolls and drawn into holes in the lags or strips which. formthe cylinder, in the same manner as above described, and I desire toinclude such brushes as part of my invention.

Another feature consists in combining with a brush of the naturedescribed a receptacle and means for containing and distributing bronzewhile the brush is in use, as hereinafter explained, thus making a'veryconvenient and serviceable device for applying bronze by hand. The brushframe or back B is made of the form indicated, and is provided with acen tral longitudinal aperture, d, upon the top; or within the auxiliarypiece B of the back B, I arrange a receptacle or hopper, G, forcontainingbronze-powder. In the bottom of the hopper is a gate or slide,D, for closing the aperture d, and said gate is provided with aclosing-spring,f, (see dotted line, Fig. 1,) and with a knob, D, bymeans of which the gate can be opened by pressure of the finger thereon.A close-fitting cover, F, is provided for closing the top of thereceptacle 0,-said cover being furnished with buttons 9 or othersuitable fastening devices. The working-face of the brush has a centralopening corresponding with the aperture d,and permits the free passageof bronze-powder, accordingly as he applies more or less pressure to theknob D.

What I claim as of my invention, and desire to secure by Letters Patent,is

1'. A brush the working-faceof whichis composed of small rolls of clothor cotton fabric drawn into and secured in a backing of. wood or othersuitable material, substantially as hereinbefore set forth.

2. The combination, with a brush having a working-face composed of smallrolls of cloth drawn into and supported by a rigid backing, as setforth, of areceptacle for bronze-powder,

and means for regulating the flow of bronze therefrom, substantially asset forth. r5

3. The combination of the brush A, the backing-piece B B, having thehopper O, with central longitudinal aperture, d, and the gate withoperating-knob D, substantially as and for the purposes described. 1

Witness my hand this 10th day of February, A. l). 1883.
